Beyonce has praised a fan who posted a viral video of herself dancing to the singer's track Get Me Bodied before her double mastectomy surgery.

Deborah Cohan shared the clip of herself and her whole medical team at San Francisco's Mt. Zion Hospital laughing as she prepared to undergo the procedure to have both her breasts removed this week (begs04Nov13).

Before the surgery, Cohan wrote on her website, "I will be dancing in my little hospital gown and bouffant cap in the Mt. Zion operating room with the surgical and anesthesia teams...

"I have visions of a healing video montage. Nothing brings me greater joy than catalyzing others to dance, move, be in their bodies..."

The video has since went viral and caught the attention of the pop superstar, who wrote on Facebook.com on Thursday (07Nov13), "Deborah, you are awesome!"
